Link body for jewelry purposes



N 1931- v H. STOCKERT LINK BODY FOR JEWELRY PURPOSES Filed March 18.1929 Patented Nov. 3, 1931 HERMANN STOGKERT, OF PFORZHEIM, GERMANY LINKBODY FOR JEWELRY PURPOSES Application filed March 18, 1929, Serial No.348,079, and in Germany November 10, 1928.

The invention relates to a hollow link body for use chiefly for makingarticles of jewelry such as necklaces, bracelets and the like.

The novelty consists in that the walls to- [5 gether with the bottomorend walls consist of one single continuous piece obtained by stamping.

Several embodiments of the invention are illustrated by way of examplein the accom- 1 panying drawings in which:

Fig. 1 shows in perspective view a dieshaped link-body.

Fig. 2 shows in plan view the corresponding stamped piece. 15 Fig. 3shows a portion of an articulated band with three consecutive die-shapedlinks.

plate of which the cylindrical link is made.

Fig. 9 is a cross-section on line 99 of Fig. 8.

Fig. 10' shows a longitudinal central section of the cylindrical bodyillustrated in Fig. 7.

F ig. 11 shows a portion of an articulated link band composed of threecylindrical links. Fig. 12 is a perspective View of a conical link.

Fig. 13 shows in plan view the stamped plate from which the conical linkillustrated in Fig. 12 is formed.

Fig. 14 shows a portion of an articulated link band composed oftwoconical link bodies and one cylindrical link body.

The forms of construction illustrated in the accompanying drawings areonly shown by way of example. Without departing from the fundamentalidea of the invention link bodies of other shapes can evidently be made,in the same manner .e. g. quintagonal, octagonal, and other multi-sidedprisms, as well as pyramids and frustrum of a pyramid, frustrum of acone and others.

The stamped plate comprises, according to the invention, all the sidesof the body, i. e. not only the side or wall porti n5 (1, b, c, d butalso the bottom or end faces 6, f, g, it, these latter being connectedwith the side or wall portions a, b, c, d by means of a short neck 2',la, Z, m so that, when being folded over for the purpose of forming thelink body from the stamped plate, they can be brought into a lowerposition corresponding to about the thickness of the material, wherebythe outer sides of the bottom portions 6, f, g, h are absolutely orapproximately flush with the end edges n, 0, p, g of the side or wallportions a, b, 0, d of the link bodies.

In order to prevent open joints, such as might form between the sides orwall portions a, b, c, d and the end portions e, f, g, h a groove 7" ispressed along the end edges n, 0, p, g with which the edges of thebottom portions e, f, g, k engage when the link-body is being formed.Consequently it is not necessary to solder along the edges.

The bottom plates e, f, g, k are outwardly curved in order to limit thecontact surfaces to a single point when the link members are threaded ona carrier 8 and especially in order to prevent the edges and corners ofone link body rubbing against the end faces of adjacent links. Moreoverone or more holes t are provided in the end plates to allow the passageof the carrier 8.

The individual links may be fashioned and decorated as desired,specially the side or wall plates a, b, 0, (Z may be decorated bypressing engraving, guilloching, enamelling, by setting with stones orin any other manner.

The chief advantage of the link body consists in the hollow, cheapproduction from a single stamped plate whereby the fixing of the endplates 6, fig, h in the side or wall portions a, b, 0, d with which theyare already rigidly connected, is considerably simplified and improved.

I claim 1. A hollow link-body for jewelry purposes, in which the sideplates and end plates are formed of one single stamped plate the endplates being connected to the corresponding side plates by means of ashort neck adapted to enable said end plates to be bent so that theyassume'a position lower by about the thickness of the material than theadjoining edges of said side plates whereby the outer surfaces of saidend plates are approximately flush with said adjoining edges 2. A hollowlink-body for jewel purposes, in which the side plates and en plates areformed of one single stamped plate the end plates being connected to thecorresponding side plates by means of a short neck adapted to enablesaid end plates to be bent so that they assume a position lower by aboutthe thickness of the material than the adjoining edges of said sideplates whereby the outer surfaces of said end plates are approximatelyflush with said adjoining edges, said adjoining edges being providedwith a groove into which the edges of the end plates engage to preventformation of 0 en joints.

In testimony whereof I my signature.

HERMANN STOCKERT.
